Guns and Lipstick(1995) [Mary Harris]: Shot to death (off-screen) by Sonny Landham in her dressing room. Her body is not shown; we only learn of her death when Robert Forster informs Sally Kirkland in his office.

Black Scorpion II: Aftershock (1997) [Professor Ursula Undershaft/Aftershock]: Killed in an explosion when she throws herself into her earthquake device to stop it from destroying the city. (Note: The subsequent TV series brought Sherrie back as the same character, retroactively revealing that she survived the explosion. However, since the original movie portrayed the blast as being fatal, I decided to go ahead and include it.)

Final Payback (1999) [Tanya]: Stabbed in the chest with her own knife during a struggle with Richard Grieco in a hotel room.
